Laser tracking measurement system and method

The invention discloses a laser tracking measurement system and method. The laser tracking measurement system comprises a laser, a spectroscope, a first galvanometer, a second galvanometer, a positiondetector and a tracking control module, wherein laser light generated by the laser is emitted to the first galvanometer through the spectroscope, is reflected by the first galvanometer, is emitted tothe second galvanometer, is reflected by the second galvanometer and is emitted to a detection target; laser beams reflected by the detection target sequentially pass through the second galvanometer,the first galvanometer and the spectroscope and are reflected to the position detector; and the tracking control module is used for acquiring angle information of the first galvanometer and the second galvanometer and position information in the position detector, and sending out a galvanometer deflection angle control signal to control the first galvanometer and the second galvanometer to be deflected for enabling the las
